SolidWorks Initial Model

The 2D tools used in this model include the line tool, circle tool, tangent arc tool, and the 3 point arc tool. The lines and arcs were defined by either coincident or tangent relationships. The 3D tools were used to extrude the 6-circle contraption and three rings at the bottom to 10mm. The extruded cut was used for the middle ring to make the hole. The base of the sketch was extruded to 5mm. In the end, it was filleted to 2mm. Mass = 56.87 grams Volume = 55556.51 cubic millimeters Surface area = 24811.42 square millimeters
